70g tank, 20g sump, currently no extra rock in it.
Rock is from my 125g tank. I pulled it out and left it outside for a few months to kill it off (aptasia and clam predator - can't think of name off top of head).
I started cycling that rock again two months ago, also used aqua vitro seed to start. Tossed in pellets every now and then to keep cycle going.
I do have marine pure balls AND a the large block in the sump of my 125g. I can move them but had wanted to dip/quarantine before I move to this tank, just didn't have time.
My plan is to go minimalistic rock work in display. May remove the Tonga at some point.
I guess my question is why do these bacteria additives claim to make tank fish ready? I'm assuming ammonia is from sand, I bought the dry fine stuff from my lfs. Other than that I shouldn't have an ammonia source in the tank.
